The -12V is almost certainly used for deriving the tuning voltage. The unit can generate a tuning voltage of -5V to +5V. To do this it needs a negative supply... and there does not seem to be an on board bias generator for generating the negative DAC supply. Becuase of this, for best tbolt performance, you probably should not use a schlocky -12V supply.
